CONFIGURATION REGISTER B15 B14 B13 B12 B11 B10 B9 B8 RFU RFU RFU RFU RFU HYST [1:0] SHDN B7 B6 B5 B4 B3 B2 B1 B0 TCRIT_LOCK EVENT_LOCK CLEAR EVENT_STS EVENT_CTRL TCRIT_ONLY EVENT_POL EVENT_MODE Bit Description B15:B11 Reserved for future use; can not be written; should be ignored; will typically read as 0 B10:B9 (Note 9) 00: Disable hysteresis 01: Set hysteresis at 1.5°C 10: Set hysteresis at 3°C 11: Set hysteresis at 6°C B8 (Note 13) 0: Thermal Sensor is enabled; temperature readings are updated at sampling rate 1: Thermal Sensor is shut down; temperature reading is frozen to value recorded before SHDN B7 (Note 12) 0: Critical trip register can be updated 1: Critical trip register cannot be modified; this bit can be cleared only at POR B6 (Note 12) 0: Alarm trip registers can be updated 1: Alarm trip registers cannot be modified; this bit can be cleared only at POR B5 (Note 11) 0: Always reads as 0 (self−clearing) 1: Writing a 1 to this position clears an event recording in interrupt mode only B4 (Note 10) 0: EVENT output pin is not being asserted 1: EVENT output pin is being asserted B3 (Note 9) 0: EVENT output disabled; polarity dependent: open−drain for bit B1 = 0 and grounded for B1 = 1 1: EVENT output enabled B2 (Note 15) 0: event condition triggered by alarm or critical temperature limit crossing 1: event condition triggered by critical temperature limit crossing only B1 (Notes 9, 14) 0: EVENT output active low 1: EVENT output active high B0 (Note 9) 0: Comparator mode 1: Interrupt mode 9. Can not be altered (set or cleared) as long as either one of the two lock bits, B6 or B7 is set. 10.This bit is a polarity independent ‘software’ copy of the EVENT pin, i.e. it is under the control of B3. 11. Writing a ‘1’ to this bit clears an event condition in Interrupt mode, but has no effect in comparator mode. When read, this bit always returns 0. Once the measured temperature exceeds the critical limit, setting this bit has no effect (see Figure 12). 12.Cleared at power-on reset (POR). Once set, this bit can only be cleared by a POR condition. 13.The TS powers up into active mode, i.e. this bit is cleared at power-on reset (POR). When the TS is shut down the ADC is disabled and the temperature reading is frozen to the most recently recorded value. The TS can not be shut down (B8 can not be set) as long as either one of the two lock bits, B6 or B7 is set. However, the bit can be cleared at any time. 14.The EVENT output is “open-drain” and requires an external pull-up resistor for either polarity. The “natural” polarity is “active low”, as it allows “wired-or” operation on the EVENT bus. 15.Can not be set as long as lock bit B6 is set. |
